Hi, first time poster here... I have two RM IB kids (one graduated years ago and the second one is current IB senior) so maybe I can help. First of all, between, WJ and RM/IB you can't go wrong. Both are excellent programs. As someone said above, IB is a magnet program and you must be tested to get in. It's open county wide to 8th graders. Each year more or less than 1000 kids apply, about 100 kids get in. The application and testing process is pretty intensive. If you live within feeder school area, however, you can do one of two things -- you can apply and test in to IB program (just like other program kids) or use MYP program (no testing/no app) to join IB at 11th grade as someone stated above. Not too many kids use this path as I understand it - only about 10 or so. It should be noted however IB program pushes kids very, very hard. It is not for everyone. You need to make sure your child can and willing to put in time and effort. If you have specific questions, I can try to answer. Hope this is helpful.
